Abstract 1122‐000096: Transradial Results in Faster Recanalization in Left Anterior Circulation Stroke and Bovine Arch

Introduction : We compared technical and clinical outcomes of transradial (TRA) versus transfemoral (TFA) access for mechanical thrombectomy (MT) of acute ischemic stroke (AIS) due to large vessel occlusion (LVO) in the left anterior cerebral circulation of bovine origin. Methods : A single‐center retrospective review of a prospectively maintained neuro‐interventional database from a large volume service in a tertiary academic center. Procedural metrics, technical, and clinical outcomes data were collected and analyzed for patients who underwent MT presenting with AIS and LVO in the left anterior circulation of bovine origin. Primary outcomes included the average number of passes, single first effective pass, rate of successful recanalization (thrombolysis in cerebral infarction (TICI) score ≥ 2b), 3‐month disability modified Rankin Scale (mRS) score ≤2, time from skin puncture to microcatheter placement and recanalization. Results : Between January 2018 and January 2021, 26 patients (TRA = 13, TFA = 13) underwent MT. The TRA cohort had a significantly shorter time in minutes for skin puncture to microcatheter placement (TRA: 17.0± 5.8 vs TFA: 35.4± 20.5, P = 0.0001), shorter skin puncture to recanalization (TRA: 34.0± 15.6 vs TFA: 58.1± 34.6, P = 0.01), and shorter total fluoroscopy time (TRA: 13.8±9.4 vs TFA: 29.5±18.0, P = 0.03). The 3‐month mRS score of 0–1 was higher in the TRA group (38.5% vs 7.69%, P = 0.06). Conclusions : In patients with LVO in the left anterior cerebral circulation of bovine origin, right TRA access permits more direct navigation and provides a stable platform resulting in shorter procedure times and faster recanalization with the potential to improve functional outcomes.
